A randomized, controlled trial evaluating the efficacy of an online intervention targeting vitamin D intake, knowledge and status among young adults

Table 3 Mean (SD) vitamin D intake (IU/day) among participants at pre- and post-test (M = 128 days, SD = 31)^*

⁺Note: At post-test, n = 48 for control group and n = 37 for males in totals for foods/beverages and total vitamin D, due to a missing data point
*Significant differences are indicated in bold with subscript lettering. No significant difference found in mean vitamin D intake between study groups at pre- or post-test, p > 0.05
^aTotal mean daily vitamin D intake increased significantly among the full sample from pre- to post-test, t(88) = 5.37, p < 0.001
^bSupplemental vitamin D intake increased significantly from pre- to post-test in intervention group, t(40) = 3.37, p < 0.01 but not control group, p > 0.05
^cTotal mean vitamin D intake increased significantly from pre- to post-test in intervention group, t(40) = 2.78, p < 0.01 but not control group, p > 0.05
